SUPPORTER FOR SI ERAYING-TOWERS.

Specification of Letters Patent.

Patented Dec. 3, 1907.

Application filed February 28, 1907. Serial No. 359,780.

To all whom it may concern:

Be it known that 1, DAVID SNE L,a citizen of the United States, residingat Gasport, in the county of Niagara and State of New York, haveinvented a new and useful Supporter for Spraying-Towers, of which thefollowing is a specification.

This invention has reference to improvements in supporters for sprayingtowers, and its object is to provide an adjustable means for holding thespraying nozzles in any desired position whereby spraying compositionsmay be thrown on to trees infested with various parasites, or that areliable to become so infested.

The invention consists essentially in a tower-holding rod adjustable ina vertical plane around a horizontal axis, with means for holding thesame in the adjusted position, together with a support for the structurewith provision for rotating the entire structure on a vertical axiswhereby the nozzle holder may be moved through a circular path in ahorizontal plane.

The invention will be fully understood from the followin detaileddescription taken in connection with the accompanying drawing s formingpart of this specification, in

' which,

Figure 1 is an end elevation of the machine; Fig. 2 is a side elevation;and Fig. 3 is a plan view of the machine with the towersupporting rodremoved.

Referring to the drawings, there is shown a support for the towercomprising a horizontal ring or annular band 1 at two diametric allyopposite points of which are secured uprights 2-3 approaching each othertoward the upper end and there secured to diametrically opposite pointsof a vertically arranged ring 4. The uprights 23 have braces 5 attachedto them about midway between their upper and lower ends, and thesebraces are spread apart at their lower ends and are there fast to theband 1. Extending diametrically across the ring 4 in a horizontaldirection and about coincident with the point of juncture therewith ofthe standards 23 is a cross-bar 6, and braces 7 connect the lowerportion of the ring 4 with the standards 23.

Diametrically across thering 1 in line with the point of juncture of thestandards 2-3 is a brace or bar 8, and through this bar extends a pivot9 in the axial center of the ring 1, the pivot 9 entering whateversupport the ring 1- may rest upon, whether the same be a wagon-body orany other means whereby the device may be transported from tree to tree.

Upon the axis or center of the ring 4 there is hung by means of a pivot10 a bar 11, one end of which extends downward beyond the ring 4 and isthere connected by a spring12 to a clip 13 fast on the ring 1, or, ifdesired,

on the bar 8, and this clip may be fixed in any position by means of athumb-screw 14, i

or the frictional contact of the clip with the ring 1 may be sufficient.The other end of the rod 11 extends upward beyond the ring 4 to anydesired distance and is designed to carry a tower 15 having a number ofnozzles 16 above the upper end of the rod 11, and this tower may besecured to the rod 11 by means of suitable clips 17.

A spring 12 tends to move the lower end of the rod 11 until the rod andspring are about in line one with the other. Now, if the rod 11 beturned on its pivot against the action of the spring and the pin 18 beplaced in one of the holes 19, of which there isa series formed throughthe ring 4, the tension of the spring will hold the rod 1 1 against thispin as a stop, and the tower will therefore be held in the adjustedposition while the operation of spraying is proceeding. In order tofacilitate the adjustment of the tower 15, this latter carries amanipulating handle 20.

When the operation of spraying is proceeding the operator may move theentire support about the pivot 9 to direct the nozzles to any point ofthe tree being sprayed that he may desire, and he may also adjust therod 11 through any vertical are he may desire and there set it by'meansof one of the pins 18 inserted in one of the holes 19 and the rod willthere be held against accidental displacement by the pull of the spring12.

Should it be desired to tighten or loosen the spring 12, the clip 13 maybe moved to any desired point on the ring 1, or on the bar 8 if the clipbe placed on this said bar.

It will be seen that by making the entire structure of band metal, it ismade amply strong for the purpose and at the same time is so light as tobe readily carried upon a wagon which may also contain the spraypum andthe supply of spraying liquid. At the same time the cost of manufacturewill be small because the parts may all be made of the band metal ofcommerce, put together by rivets or bolts, so that the only labornecessary in the construction of the device will be the cutting of theband metal into the roper lengths and the riveting together of theparts.

The rod 11 may either be made of suitably stiffened metal or of wood.

It will be understood, of course, that the structure may be carried upona suitable support, such as a boat, behind the wagon.

1. A supporter for a spraying tower comprising a circular frame arrangedvertically and having a peripheral series of perforations, a bar pivotedto the center or axis of the frame, stops adapted to said perforationsand in the path of the bar or tower support, and a spring tending tohold the bar against a stop in its path.

2. A supporter for a spraying tower com prising a horizontal circularframe, a bar diametrically across the same, a pivot insaid bar in theaxis of the circular frame, standards rising from diametrically oppo- 1site points of said frame, a vertical ring} mounted on the upper ends ofsaid stand- 1 ards, a rod for carrying the tower pivoted 3 in the axisof said vertical frame for move- I ment through a vertical arc, a springconi l I l nected to the lower end of said bar and to a fixed point onthe supporting frame, and a stop pin adapted to any one of a series ofperforations in the vertical frame and arranged to be locked in the pathof the towercarrying bar.

3. A supporter for a spraying tower com prising a horizontal framemovable about a vertical axis, a vertical frame supported thereby andmovable therewith, a towercarrying bar supported at the axis of saidvertical frame to move through a vertical arc, a stop adapted to any oneof a number of perforations in said vertical frame and in the path ofthe tower-carrying bar, a spring secured to the tower-carrying bar atthe end opposite that carrying the tower nozzles, and a clip adjustablysecured to a fixed portion of the lower part of the frame and connectedto the end of the spring remote from that secured to the tower-carryingbar.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
